Effect of ancestry on haplotypes in chronic periodontitis.

Chronic periodontitis is caused by an inflammatory reaction of the periodontal tissues and alveolar bone. This inflammation is caused by periodontopathic bacteria located in the subgingival biofilm, resulting in inflammatory reactions that may lead to loss of attachment. This tissue destruction is a consequence of host immune and inflammatory responses to specific periodontal pathogens and their metabolic products.

[Evaluation of oral health actions in the Family Health Program in the Mosqueiro district, Pará State, Brazil].

The extension of Brazil's Family Health Program Teams through the introduction of Oral Health Teams (OHT) as required by Decree N degrees 1,444 dated December 28, 2000, was an important step in the restructuring of the Oral Healthcare System, ensuring easier access to good quality dental care and treatment for less privileged segments of the population. In the Mosqueiro district of Pará State, an Oral Health Team was added to the Family Health Program in 2002, working closely with the local community through home calls and school visits, as well as at the Family Health Unit. In order to assess these Oral Health activities, 103 users of the Family Health Program Unit responded to a questionnaire with closed and semi-open questions in July 2004.
